Chlorella vulgaris (US EPA Guideline EPA/600/4-90/027) (US EPA Guideline EPA/600/4-90/027) (literature information) Data obtained by analogy conclusion Aquatic micro-organisms Conclusion obtained by structural analysis and intended use Based on available data, the classification criteria are not met Assessment / classification Persistence and degradability In aqueous solution, potassium sulphate is completely dissociated into the potassium ion (K +) and the sulfate anion (SO42-). Hydrolysis of potassium sulfate does not occur. Due to the inorganic nature of the substance standard testing systems are not applicable. Bioaccumulative potential Potassium sulfate completely dissociate in water forming potassium ions and sulfate anions. Potassium sulfate has a low potential for bioaccumulation based on physicochemical properties. Mobility in soil Based on the high water solubility and the ionic nature, potassium sulphate is not expected to adsorb, however, due to ion exchange process, sulfates can be retained in soil, both by incorporation into organic matter (e. g. as sulfate esters of humic acids) and adsorbed to soil particles such as hydrous iron and aluminum sesquioxides. Other adverse effects None specified. 13. DISPOSAL CONSIDERATIONS Disposal should be in accordance with applicable federal and state laws. It is the responsibility of the waste generator to determine the toxicity and physical properties of the material generated to determine the proper waste identification and disposal method in compliance with applicable regulations.
